不同钾肥喷施对烤烟生长和产质量的影响

Effects of Spraying Different Kinds of Potassium Fertilizers on Growth,Yield and Quality of Flue-cured Tobacco

[目的]探索出适合烤烟K326最佳的钾肥喷施方案。[方法]研究不同种类钾肥喷施对烤烟K326生长及产质量的影响。[结果]喷施有机钾肥和硫酸钾肥均有利于烤烟的生长发育和品质的提高,但喷施有机钾肥的效果更好,能提高烟叶水溶性总糖、还原糖和钾的含量,降低总氮和烟碱含量,使初烤烟叶内在主要化学成分更趋于协调。[结论]该研究可为烤烟的钾肥施用提供参考。

[ Objective ] To explore the preferred fertilization plan of spraying potassium fertilizers for K326. [ Method ] Field experiment was conducted to study the effects of spraying different kinds of potassium fertilizers on growth, yield and quality of flue-cured tobacco （K326）. [ Result ] Spraying organic potassium fertilizer and potassium sulfate fertilizer could enhance growth and quality of tobacco leaves. And the effect of spraying organic fertilizer was better,which could increase the content of total water-soluble sugar ,reducing sugar and potassium ,reduce the content of total nitrogen and nicotine, make harmonious chemical components of flue-cured tobacco. [ Conclusion ] The research can offer reference for spraying potassium fertilizers on flue-cured tobacco.
